Determining the Impact of Structural Friction Parameters in the Body of an Assembled Cutter on the Damping of Its Amplitude and Self-oscillations

Year: 2025

Type: article

Abstract: The paper examines the potential use of dry friction in designing metal-cutting tools to dampen vibration energy. A mathematical model of the self-oscillating system "machine-fixture-tool-workpiece" has been developed and analyzed, considering structural friction within the assembly of the cutting tool. The study has investigated structural friction's impact on the cutter body's self-oscillation amplitude at the cutter tip and the workpiece surface. The paper demonstrates the possibility of effectively reducing the amplitude of self-oscillations in the system through the optimal selection of tool parameters.
